CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit of Korean Patent Application No. 10-2016-0122032, filed on Sep. 23, 2016 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND 1. Field

Embodiments of the present disclosure relate to a refrigerator, more particularly to a refrigerator having a shelf assembly in a storage compartment.

2. Description of Related Art

A refrigerator is an apparatus configured to keep foods fresh by having a storage compartment storing foods and a cool air supply apparatus to supply cool air to the storage compartment. In the storage compartment of the refrigerator, a shelf assembly is provided to support goods for improving the efficiency of the storage space.

Since the shelf assemblies spaced apart from each other in the vertical direction divides the inside of the storage compartment into a plurality of spaces, the utilization of the storage space may be improved and it may be possible to store goods easily. In recent, since the size of the refrigerator has increased, there may be difficulties in taking out the goods deeply placed in the rear side of the shelf. Therefore, a refrigerator provided with a moving-shelf assembly has been manufactured as well as a refrigerator provided with a fixed-shelf assembly.

In general, a refrigerator includes components for a refrigeration cycle. In basic, the refrigerator is a device to refrigerate or freeze goods stored in a storage compartment by using cool air generated by the components for the refrigeration cycle.

As for the refrigeration of the refrigerator, a compressor compresses refrigerant gas in the refrigerator to make high-temperature and high-pressure refrigerant gas, and the refrigerant is sent to a condenser. The condenser condenses the refrigerant by releasing the refrigerant gas and liquefies the refrigerant.

The liquefied refrigerant is in a state where it is easily vaporized at a low temperature in a capillary tube while being at the low pressure, and then the liquefied refrigerant is vaporized again in the low temperature cooler. Since the refrigerant absorbs the heat of vaporization generated at this time, the ambient air is deprived of the heat from the refrigerant and the temperature is lowered.

Air at the low temperature, i.e., cold air, is discharged to the inside of the storage compartment of the refrigerator and thus the refrigeration or the freezing is performed. The vaporized refrigerant gas is sent to the compressor again and then the above process is repeated. Such a cooling method is called as a gas compression type, and this method is the most widely used method for general households because it is efficient and has excellent cooling power.

On the other hand, a structure capable of fixing the shelf assembly may be provided in a panel forming one side of the storage compartment. However, cold air discharged into the storage compartment may be blocked by the shelf assembly coupled to the panel.

In the machinery room 80, a compressor 81 configured to compress refrigerant, a condenser (not shown) configured to condense the compressed refrigerant, and a refrigerant expansion device (not shown) configured to expand the compressed refrigerant may be installed.

FIG. 3 is a view illustrating a case in which a position of a shelf assembly supported by a panel is changed, in the refrigerator in accordance with an embodiment of the present disclosure.

Referring to FIG. 3, a position of the shelf assembly 40 may be changed by being supported by the panel 50 forming one surface of the storage compartment 20. The panel 50 may include a rear panel 50 forming the rear surface of the storage compartment 20.

The panel 50 may include a plurality of support guide extended in the transverse direction and arranged in the longitudinal direction. The transverse direction may represent a X axis direction and the longitudinal direction may represent a Z axis direction among the X, Y, Z coordinates.

As the shelf assembly 40 is mounted to or detached from the plurality of support guides 51, it may be possible to adjust a height in which the shelf assembly 40 is coupled to the panel 50. The shelf assembly 40 may be moved in the transverse direction along the plurality of support guides 51. The number of the support guide 51 may be determined according to the height of the panel 50.

The plurality of the shelf assemblies 40 may be coupled to the plurality of support guides 51 in the transverse and longitudinal directions. Each of the size of the shelf assembly 40 supported by the plurality of support guides 51 may be different from each other.

A transverse width of the shelf assembly 40 may be properly selected. The transverse width of the shelf assembly 40 may correspond to a half of a transverse width of the panel 50 to which the shelf assembly 40 is coupled. Alternatively, the transverse width of the shelf assembly 40 may correspond to a quarter of a transverse width of the panel 50 to which the shelf assembly 40 is coupled.

FIG. 4 is a side cross-sectional view illustrating a coupling structure between the shelf assembly and the panel in the refrigerator in accordance with an embodiment of the present disclosure.

Referring to FIG. 4, the shelf assembly 40 may include a shelf 41 on which goods stored in the storage compartment 20 are loaded and a frame 42 supporting the shelf 41. The frame 42 supporting the shelf 41 may be detachably coupled to the plurality of support guides 51.

The frame 42 may include a locking portion 420 coupled to the plurality of support guides 51. The locking portion 420 may include a first locking portion 420 a and a second locking portion 420 b which are coupled to two support guides placed adjacent to each other, among the plurality of support guides 51.

The first locking portion 420 a may be coupled to a support guide 51 placed in the upper side between two support guides, which are placed adjacent to each other and to which the locking portion 420 is coupled, and the second locking portion 420 b may be placed in the lower side of the first locking portion 420 a.

The first locking portion 420 a may be formed in a direction parallel in the shelf 41, i.e., front and rear direction, to support the shelf 41, and the second locking portion 420 b may be formed in a diagonal direction. The front and rear direction may represent a Y axis direction and a diagonal direction may represent a direction between the Y axis and a Z axis in the X, Y, Z coordinates.

A shape where the locking portion 420 (the first locking portion 420 a and the second locking portion 420 b) is coupled to the panel 50 may form a right triangle. Therefore, a coupling between the shelf assembly 40 and the panel 50 can be solid.

One end portion of the first locking portion 420 a may be curved in the lower side toward the second locking portion 420 b (the Z axis direction), and one end portion of the second locking portion 420 b may be curved in the direction parallel with the shelf 41 (the Y axis direction).

The frame 42 may include a roller 421 installed in the locking portion 420. A direction of the axis of rotation of the roller 421 may correspond to the vertical direction (the Z axis direction). The roller 421 may include a first roller 421 a installed in the first locking portion 420 a and a second roller 421 b installed in the second locking portion 420 b.

The plurality of support guides 51 may include a support groove 510 formed in the front surface of the panel 50 and a support portion 511 formed in the rear surface of the panel 50. A plurality of the support grooves 510 and support portions 511 may be provided. The number of the support portion 511 may be identical to the number of the support groove 510.

The support portion 511 may be formed in a square shape whose one surface is open, so as to cover the support groove 510 in the rear side of the panel 50, wherein the square shape is similar with a shape of ‘C’.

The locking portion 420 may be inserted into the plurality of support guides 51 and fixed by being supported by the plurality of support guides 51. When goods are loaded on the shelf 41 supported by the frame 42 fixed to the plurality of support guides 51, the rotational force may be applied to the shelf assembly 40 by the weight moment of the goods.

The locking portion 420 may be lifted to the up side in the plurality of support guides 51 by the rotational force applied to the shelf assembly 40. When the locking portion 420 is inserted into the plurality of support guides 51, the first roller 421 a installed in the first locking portion 420 a may be supported by the front inner surface corresponding to the first roller 421 a and the second roller 421 b installed in the second locking portion 420 b may be supported by the rear inner surface corresponding to the second roller 421 b.

Despite the rotational force applied to the shelf assembly 40, the shelf assembly 40 may be stably fixed to the panel 50.

When the locking portion 420 is detached from the plurality of support guides 51, the shelf assembly 40 may be separated from the panel 50. As the shelf assembly 40 is inserted into two support guides 51 disposed adjacent to each other among the plurality of support guides 51 which are arranged in the longitudinal direction, a height to which the shelf assembly 40 is coupled to the panel 50 may be changed.

When the locking portion 420 is inserted into the plurality of support guides 51, the locking portion 420 may make contact with the plurality of support guides 51. Due to the frictional force generated by the contact between the locking portion 420 and the surface of the plurality of support guides 51, the shelf assembly 40 may be fixed to the panel 50 without moving in the transverse direction (the X axis direction).

Therefore, although an external force in the transverse direction (the X axis direction) is applied to the shelf assembly 40, the shelf assembly 40 may be stably fixed without movement.

When the shelf assembly 40 is fixed to the panel 50, a surface of the support portion 511, by which the roller 421 is supported, may be different from when the shelf assembly 40 is moved in the transverse direction (the X axis direction) along the plurality of support guides 51.

When an external force is applied to the shelf assembly 40 in the upper side (the Z axis direction), the locking portion 420 coupled to the plurality of support guides 51 may be lifted in the upper side (the Z axis direction).

Therefore, the surface of the support portion 511 supporting the first roller 421 a installed in the first locking portion 420 a may be changed from the front inner surface of the support portion 511 to the rear inner surface of the support portion 511. The surface of the support portion 511 supporting the second roller 421 b installed in the second locking portion 420 b may be changed from the rear inner surface of the support portion 511 to the front inner surface of the support portion 511. That is, the contact surface between the locking portion 420 and the plurality of support guides 51 may be reduced.

As the contact surface between the locking portion 420 and the plurality of support guides 51 is reduced, the frictional force caused by the surface contact between the locking portion 420 and the plurality of support guides 51 may be reduced. Therefore, when an external force in the transverse direction (the X axis direction) is applied to the shelf assembly 40, which is lifted in the upper side (the Z axis direction), the shelf assembly 40 may be moved in the transverse direction (the X axis direction) in the panel 50 by the rolling movement of the roller 421.

FIG. 5 is a view illustrating a structure for discharging cold air via a hole in the support portion in the refrigerator in accordance with an embodiment of the present disclosure.

Referring to FIG. 5, the support portion 511 may include a hole 512 delivering cold air generated by the cool air supply apparatus to the support groove 510. A plurality of holes 512 may be provided. The hole 512 may be disposed in the upper side in the rear surface of the support portion 511. The plurality of holes 512 may be arranged in the transverse direction (the X axis direction).

FIG. 5 illustrates that the hole 512 is disposed in the upper side in the rear surface of the support portion 511, but the position of the hole 512 is not limited thereto. Therefore, the hole 512 may be disposed in any position as long as the position of the hole 512 does not affect the coupling between the locking portion 420 and the inside of the support portion 511. For example, the plurality of holes 512 may be disposed in upper surface of the support portion 511.

The height of the support groove 510 in the longitudinal direction (the Z axis direction) may be higher than the height of the locking portion 420, which is coupled to the panel 50, in the longitudinal direction (the Z axis direction). Therefore, the plurality of support guides 51 may include a cold air discharging portion 52 discharging cold air to the storage compartment 20 via the support groove 510 although the locking portion 420 is inserted into the plurality of support guides 51. That is, the cold air may be discharged to the inside of the storage compartment 20 in a cold air discharge direction (A).

Therefore, although the shelf assembly 40 is inserted into the plurality of support guides 51, the cold air may be discharged into the inside of the storage compartment 20 via the cool air discharging portion 52 without the interference of the shelf assembly 40.

The cold air discharging space of the support groove 510 may act as a space which is needed for the shelf assembly 40 to be lifted in the upper side (the Z axis direction), wherein the lift of the shelf assembly 40 is needed to move in the transverse direction (the X axis direction) along the plurality of support guides 51.

Therefore, while supporting the shelf assembly 40, the plurality of support guides 51 may perform the function of the cool air discharging portion 52 discharging the cold air generated by the cool air supply apparatus, to the storage compartment 20.

FIG. 6 is a view illustrating a cold air discharging portion of a panel in a refrigerator in accordance with another embodiment of the present disclosure.

Referring to FIG. 6, a panel 50 may include a cold air discharging portion 520 disposed in the upper portion or one side of the panel 50 and configured to discharge the cold air generated by the cool air supply apparatus to the storage compartment 20. The cold air discharging portion 520 may be separately formed from the plurality of support guides 51.

The cold air discharging portion 520 may include a first cold air discharging portion 520 a formed in a shape similar with the shape of the plurality of support guides 51 and extended in the transverse direction in the upper portion of the front surface of the panel 50.

The first cold air discharging portion 520 a may have a shape in which a front surface and a rear surface of the panel 50 are open. However, the shape of the first cold air discharging portion 520 a is not limited thereto, and thus the shape of the first cold air discharging portion 520 a may have a variety of shapes as long as capable of discharging cold air generated by the cool air supply apparatus to the storage compartment 20. For example, a plurality of holes may be arranged in the transverse direction.

The cold air generated by the cool air supply apparatus may be discharged to the inside of the storage compartment 20 via the first cold air discharging portion 520 a. Since the shelf assembly 40 is not coupled to the upper portion of the front surface of the panel 50, the cold air may be discharged to the inside of the storage compartment 20 via the first cold air discharging portion 520 a without the interference of the shelf assembly 40.

The cold air discharging portion 520 may include a second cold air discharging portion 520 b formed in one side or both sides of the panel 50. The second cold air discharging portion 520 b may have a hole shape or a shape in which a front surface and a rear surface of the panel 50 are open.

The second cold air discharging portion 520 b may be arranged between the support portions 511 in the longitudinal direction. However, the position of the second cold air discharging portion 520 b is not limited thereto, and thus the shape of the second cold air discharging portion 520 b may have a variety of shapes and positions as long as capable of discharging cold air generated by the cool air supply apparatus to the storage compartment 20. For example, the second cold air discharging portion 520 b may be extended between the plurality of support guides 51 in the transverse direction and arranged in the longitudinal direction.

Since the cold air discharged via the second cold air discharging portion 520 b is not interfered by the shelf assembly 40, the cold air may be freely discharged to the inside of the storage compartment 20.

FIG. 7 is an exploded view illustrating the panel and the shelf assembly in the refrigerator in accordance with an embodiment of the present disclosure.

Referring to FIG. 7, the shelf assembly 40 coupled to the panel 50 may include a shelf 41 and a frame 42 supporting the shelf 41. The shelf 41 may correspond to a panel having a certain width and the square shape. However, for the user convenience, the shape of the shelf 41 is not limited thereto, and thus the shelf 41 may have a variety of shapes as long as capable of loading goods.

The shelf 41 may include a support plate 410 formed of transparent glass or synthetic resin to load goods and an edge 411 coupled to the support plate 410. The coupling method between the support plate 410 and the edge 411 may include an adhesion method using an adhesion, and a method using an additional coupling member.

The edge 411 may have a square frame shape whose a central portion is opened, so as to have a shape corresponding to the border portion of the support plate 410.

In the around of the border portion of the edge 411, a sealing member accommodation portion (not shown) in which a sealing member (not shown) is placed may be provided. The sealing member (not shown) is for the waterproof between the support plate 410 and the edge 411, and the silicone sealant may be used as the sealing member (not shown).

As mentioned above, when the support plate 410 and the edge 411 are fusion-coupled, the adhesion may occur with respect to the support plate 410 and thus it may be possible to prevent the bending (distortion) of the support plate 410 when the shelf 41 is formed by the insert injection process.

The shelf 41 may include a shelf wire (not shown) configured to prevent goods loaded on the shelf 41 from being escaped from the shelf 41. The shelf wire (not shown) may be provided on one side of the upper surface of the shelf 41.

The shelf 41 may include an edge finishing portion (not shown) configured to fix the shelf wire (not shown) and configured to improve the beauty of the shelf 41.

Two frames 42 may support the shelf 41 from opposite sides of the shelf 41. The two frames 42 may support the shelf 41 by being spaced apart the same distance from the center of the shelf 41. The shelf 41 supported by the two frames 42 may have a relatively wide width.

The shelf 41 may be inseparably coupled to the frame 42. The shelf assembly 40 may be formed by assembling the shelf 41 with the frame 42 which is formed of resin material by the injection mold method. The shelf 41 and the frame 42 may be coupled to each other by the adhesion.

The coupling between the shelf 41 and the frame 42 is not limited thereto, and thus the shelf 41 and the frame 42 may be coupled to each other by using a variety of methods.

For example, the shelf 41 and the frame 42 may be coupled to each other by using an additional coupling member (not shown) or the shelf 41 and the frame 42 may be integrally injection molded using a resin material.

FIG. 8 is a view illustrating a structure of a shelf assembly in a refrigerator in accordance with another embodiment of the present disclosure.

Referring to FIG. 8, a frame 43 may be formed such that a first locking portion 430 a is extended in the transverse direction (the X axis direction) as much as the width of the shelf 41 coupled to the frame 43. A first roller 431 a may be additionally installed in opposite end portions of the first locking portion 430 a extended in the transverse direction (the X axis direction).

A second locking portion 430 b may be placed in the center of the shelf 41. The shelf 41 supported by the frame 43 may have a relatively smaller width than the frame 42 supported by the frame 42 according to an embodiment. The shelf 41 may be inseparably coupled to the frame 43.

FIG. 9 is a view illustrating a coupling structure of a shelf assembly in a refrigerator in accordance with another embodiment of the present disclosure. FIG. 10 is a view illustrating a structure in which a shelf of the shelf assembly is fixed to a frame in the refrigerator of FIG. 9. FIG. 11 is a view illustrating an operation in which the shelf of the shelf assembly is separated from the frame in the refrigerator of FIG. 9.

The interference member 412 may be disposed in the rear side of the lower surface of the shelf 41. The fixing member 422 may be disposed in a space between two frames 42 apart from each other so as to connect the two frames 42. That is, the interference member 412 may connect two first locking portions 420 a to each other.

The interference member 412 may include a handle portion 414 having the elastic force to release the fixation of the fixing member 422. The handle portion 414 of the interference member 412 may include a first locking protrusion 413 protruding toward the upper side, and the fixing member 422 may include a second locking protrusion 423 protruding toward the lower side.

The first locking protrusion 413 of the interference member 412 and the second locking protrusion 423 of the fixing member 422 may be locked-coupled to each other in order to fix the shelf 41 and the frame 42.

The handle portion 414 may be formed of a material having the elastic force. When an external force is applied to the handle portion 414 in the lower side, the locking between the first locking protrusion 413 of the interference member 412 and the second locking protrusion 423 of the fixing member 422 may be released.

Accordingly, the fixation between the shelf 41 and the frame 42 may be released and the shelf 41 separated from the frame 42 may be taken out in the front side (the Y axis direction).

FIG. 12 is an exploded view illustrating a shelf assembly in a refrigerator in accordance with another embodiment of the present disclosure. FIG. 13 is a view illustrating a structure in which a shelf of the shelf assembly is fixed to a frame in the refrigerator of FIG. 12. FIG. 14 is a view illustrating an operation in which the shelf of the shelf assembly is separated from the frame in the refrigerator of FIG. 12.

Referring to FIGS. 12 to 14, a shelf 41 may be detachably coupled to a frame 43. The frame 43 may include a fixing member 432 configured to fix the shelf 41 and the shelf 41 may include an interference member 442 interfering the fixing member 432. The interference member 442 may be disposed in the rear side of the shelf 41.

The fixing member 432 may be disposed between a first locking portion 430 a and a second locking portion 430 b to connect the first locking portion 430 a and the second locking portion 430 b to each other. The interference member 442 may include a first locking protrusion 443 protruding toward the lower side, and the fixing member 432 may include a second locking protrusion 433 protruding toward the upper side.

The fixing member 432 may include a spring portion 435 disposed in the lower end portion of the second locking protrusion 433 and a lever portion 434 disposed in the middle of the second locking protrusion 433 to protrude toward the transverse direction (the X axis direction).

The first locking portion 430 a may include a through hole 436 through which the second locking protrusion 433 of the fixing member 432 passes in the up and down direction (the Z axis direction).

The first locking portion 430 a may include an accommodation groove 437, which has a certain height in the longitudinal direction (the Z axis direction) and is extended in the front and rear direction (the Y axis direction), to allow the second locking protrusion 433 to be placed.

As the second locking protrusion 433 placed in the accommodation groove 437 and the second locking protrusion 433 passing through the through hole 436 interfere with each other, the shelf 41 may be fixed to the frame 43.

The second locking protrusion 433 may fix the first locking protrusion 443 so that the first locking protrusion 443 is prevented from being moved to the front side. The first locking protrusion 443 and the second locking protrusion 433 may have a cylindrical shape, wherein the cross-section of the cylinder has a shape that is cut by an oblique line.

The accommodation groove 437 may be formed in the upper side of the first locking portion 430 a, and one end portion of the accommodation groove 437 may be formed until an appropriate position without being extended to one end portion of the first locking portion 430 a, and thus the first locking protrusion 443 may be fixed without moving toward the rear side.

When an external force, which is greater than the elastic force applied to the upper side by the frame 435 of the fixing member 432, is applied to the lever portion 434 of the fixing member 432 in the lower side, the second locking protrusion 433, which passed through the through hole 436 and then protruded in the upper side by the elastic force, may be lowered to the lower side and thus the interference between the first locking protrusion 443 and the second locking protrusion 433 may be released.

As the fixation between the shelf 41 and the frame 43 is released, the shelf 41 may be separated from the frame 43 and then taken out to the front side (the Y axis direction).

As is apparent from the above description, according to the proposed refrigerator, it may be possible to store goods loaded on the shelf in an easy manner and in various manners by changing the position of the shelf assembly and thus it may be possible to achieve the user convenience.

As is apparent from the above description, according to the proposed refrigerator, the panel forming one surface of the storage compartment may perform the function of the cold air discharging portion and fix the shelf assembly and thus it may be possible to save the manufacturing cost for installing the additional cold air discharging portion.
